I have atlas loot and it will not open. Unless I have Atlas installed as well the button on the minimap wont even show up. It isn't showing up in the addons section of the interface at all and no /command is working.

Same here. Have AtlasLoot updated to latest version and active.

Doesn't show any minimap button, doesn't appear under Addons in Interface and no command works.

Did you download the version like this one?

I'm using Twitch version.

I ran into this issue today. The version installed from CurseForge app didn't work (exactly as described by OP), but the version on this website did work.

go to versions on the top of the atlas loot page in the twitch launcher, or find it here on the website. and make sure your version installed is the (v8.13.00) 

and NOT the (v8.13.00-nolib) version. that seemed to be installed by default for me as well, but wont work unless you have the library installed alongside it, whereas the v8.13.00 version comes with the library 

In Curse Forge - Under the AtlasLoot Enhance Addon:

Click Versions Tab and you will see the Version "AtlasLoot-v8.13.00.zip"

Then:

Click the Vertical "..." and Mouse Over "Install Settings".

Then: 

"Uncheck - "Install Libraries Separately" - and you will see the correct version install.

I hope this helps!
